In this article, a comprehensive parameter analysis for the polling-based medium access control protocol is executed. The theoretical expressions of the relationship between network parameters and performance including delay and energy consumption are given for the first time. The specific conclusions in this article are as follows: (1) awake duration is the parameter that has the greatest impact on delay and energy consumption. Increasing the duty cycle (awake duration) will effectively reduce the delay, but will also increase the energy consumption within a certain range; (2) increasing polling duration can reduce the delay, but it will also increase the energy consumption; and (3) more forwarding nodes cause a smaller delay, and it can save the energy with modest increase of delay by reducing the polling duration. An adaptive parameter optimization polling-based medium access control protocol is proposed to optimize network performance. In this protocol, the residual energy gets fully used to increase awake duration and polling duration, which makes the delay smaller, and the network maintains a long lifetime meanwhile. Based on the results of the analysis, the adaptive parameter optimization polling-based medium access control protocol proposed in this article reduces the delay by 22.40% and increases the energy efficiency by 23.25%.

在本文中，将对基​​于轮询的媒体访问控制协议进行全面的参数分析。首次给出了网络参数与性能（包括时延和能耗）之间关系的理论表达式。本文的具体结论如下：（1）唤醒持续时间是对延迟和能耗影响最大的参数。增加占空比（唤醒持续时间）将有效地减少延迟，但也会在一定范围内增加能耗；（2）增加轮询持续时间可以减少延迟，但同时也会增加能耗。（3）更多的转发节点导致较小的延迟，并且可以通过减少轮询持续时间来节省能量，并且延迟适度增加。提出了一种基于自适应参数优化轮询的媒体访问控制协议，以优化网络性能。在该协议中，剩余能量被充分利用来增加唤醒时间和轮询时间，从而使延迟更短，同时网络保持较长的使用寿命。根据分析结果，本文提出的基于自适应参数优化轮询的媒体访问控制协议将延迟减少了22.40％，将能源效率提高了23.25％。
